Cocaine addiction is a chronically relapsing brain disease, but its neural basis is not yet well understood. Clinical reports underscore the possible importance of associative processes for regulating at least some aspects of cocaine addiction. The present study reports the effects of reversible lidocaine-induced inactivation of rostral basolateral amygdala(More)
Rationale: To investigate potential neurocognitive mechanisms underlying drug-seeking and drug-taking behavior, the effects of reversible lidocaine-induced inactivation of the lateral dorsal striatum (DST) on behavior studied in a drug maintenance/cue reinstatement model were evaluated. This region of the DST was investigated because it selectively(More)
Chemodectomas, or glomus tumours, are unusual head and neck paragangliomas. A non-invasive imaging technique, 123I-metaiodobenzylguanidine (123I-MIBG) scintigraphy, has long been used for the diagnosis of all types of paraganglioma. The aim of this study was to evaluate and compare classic 123I-MIBG scintigraphy with the more recent 111In-pentetreotide(More)
